Does acyclovir treat angular cheilitis?

Acyclovir can be used to treat angular cheilitis caused by herpes viruses. Acyclovir works by inhibiting viral DNA synthesis, thereby blocking viral replication, and has significant therapeutic effects on herpes-related angular cheilitis. However, angular cheilitis has multiple etiologies and is not limited to viral infections; it can also be caused by bacterial or fungal infections. Therefore, the underlying cause of angular cheilitis should be identified before using acyclovir. If the condition is caused by bacterial or fungal infection, appropriate antibiotics or antifungal creams should be selected under medical guidance. Please note that acyclovir should be used only as directed by a physician; self-medication should be avoided. Additionally, maintaining good oral hygiene and avoiding known allergens during treatment can aid in the recovery from angular cheilitis. If needed, please consult a qualified healthcare provider.
